如何在UITableViewCell中截断UILabel的尾部

class CustomTableViewCell: UITableViewCell {
    let label: UILabel = {
        let label = UILabel()
        label.numberOfLines = 1
        label.lineBreakMode = .byTruncatingTail
        label.font = UIFont.systemFont(ofSize: 14)
        return label
    }()
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        addSubview(label)
        
        // 使用Auto Layout布局
        label.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            label.leadingAnchor.constraint(equalTo: leadingAnchor, constant: 16),
            label.trailingAnchor.constraint(equalTo: trailingAnchor, constant: -16),
            label.topAnchor.constraint(equalTo: topAnchor, constant: 8),
            label.bottomAnchor.constraint(equalTo: bottomAnchor, constant: -8)
        ])
    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}
